Draining and filling coolant
The coolant filling volume is approx. 5.0 l.
Drain
Open the coolant cap on the expansion tank. Remove the lower engine compartment covers. Place a catch basin under the engine.
Turn the drain plug "arrow" on the radiator to the left and pull it out in the backward direction; if necessary, attach an auxiliary hose to the fitting.
Refueling
Screw in the coolant drain plug. Remove the coolant temperature sensor located on the thermostat housing. Slowly pour in coolant until it is visible in the coolant temperature sensor hole. Install the coolant temperature sensor. Slowly add coolant up to the "max" mark on the expansion tank. Close the expansion tank. Leave the engine running until the fan starts.

Check the coolant level and top up if necessary. In a warm engine, the coolant level should be at the "max" mark, and in a cold engine, between the "min" and "max" marks.
